Building a composite web service as per the user’s complex need requires using the multiple online web services available. Selecting the best web service for composition will become combinatorial problem leads to be the NP (Nondeterministic Polynomial) complete problem. To solve this problem they are proposing a framework for composite web service using ant colony ...

The increment of information in the web is too large, so search engine come to play an important role to find relation between input keywords. Policy networks are one well defined domain for research. In today’s world policy networks are used by economists and political scientists. The analysis of policy networks demands a series of ...

A compact planar monopole antenna suitable for Wireless Personal Area Network (WPAN) application is proposed. By simply modifying the periphery of a rectangular patch, effective operational band 2.95 to 16.8GHz is achieved. This band sufficiently covers the operating band, 3.1-10.6GHz, of the new Wireless Personal Area Network (WPAN) using Ultra Wide Band (UWB) technique. A ...

In this paper, the authors highlight the security needed door transmission of data on a wireless network, with the technology moving forward wireless communications has grown enormously. It is necessary to provide security for wireless data transfer as it is more vulnerable to the security attacks. 70% of the online data transfer is in the ...

Cloud computing is an upcoming field having lots of scope and research areas. In this age of technology everything from their home to office is done in the cloud and it is the future of technology. There are so many research has been done in this field to improve the quality of service. In this ...

Now-a-days, economical automobiles are developed by more of electro mechanical parts with analog interface for efficient & cost effective operation. Generally a vehicle is built with an analog driver-vehicle interface for indicating various vehicle statuses like speed, fuel level, engine temperature etc. This paper presents a design & development of cost effective solution for digital ...

In wireless sensor networks data aggregation is one of the major issues. To aggregate the data a robust aggregation framework called synopsis diffusion which combines multi path routing algorithm to accurately aggregate the data in case of failures, Nodes are compromising due to the lack of physical protection. Compromised nodes are very vulnerable to attacks ...

Ever increasing volume of back up data in cloud storage may be a vital challenge. There is a need of data management as back up windows are shrinking due to growth of information. So, to make data management scalable deduplication concept is used. It is a technique of keeping only one unique instance of data ...

In MANETs (Mobile Ad hoc NETworks), network may consist of devices with multiple characteristics in terms of transmission power, energy, capacity etc. Especially in MANETs, network may consist of devices with multiple; nodes are likely to transmit at different power levels, thereby causing conversation links varying. This causes link asymmetry problem. The link asymmetry problem ...

The Internet of Things (IoT) is the new revolution of internet after PCs and servers-clients communication now sensors, smart object, wearable devices and Smartphones are able to communicate. Everything surrounding them can talk to each other. Life will be easier and smarter with smart environment, smart homes, smart cities and intelligent transport and healthcare. Billions ...
